Cp2-Stable Classification Of 4-Manifolds With Finite Fundamental Group
PACIFIC JOURNAL OF MATHEMATICS（2021）
摘要
We show that two closed, connected 4-manifolds with finite fundamental groups are CP2-stably homeomorphic if and only if their quadratic 2-types are stably isomorphic and their Kirby-Siebenmann invariants agree.
